Firstly, from Gauss' equations and relative motion equations, the relation of control impulse and relative motion was expressed as analysis formulas and simplified based on the near circular condition. By deeply analyzing the mechanism of impulses in each directions (radial, in-track and cross-track directions) effect on relative motion respectively, two maneuvers to establish formation flying are provided: one is to utilize the impulses in radial and cross-track directions, the other is to utilize the impulses in along-track and cross-track directions. Both of the two methods can establish satellite formation flying of any configuration. The method with impulses irradial and cross-track directions needs only 3 impulses, while the method with impulses in along-back and cross-track directions needs 4 impulses. Lastly, by an example of establishing a space-circle formation flying, two maneuvers were compared with each other in the amount of impulses and fuel consuming estimation.

首先由高斯型拉格朗日轨道摄动运动方程得到轨道坐标系中控制冲量与轨道根数偏差的关系，基于近圆轨道的条件简化并带入相对运动方程，得到控制冲量与相对运动的关系表达式；通过深入分析各个方向（径向、沿迹向与轨道面法向）的控制冲量对相对运动的影响，给出了分别用径向与轨道面法向控制冲量组合和沿迹向与轨道面法向控制冲量组合实现编队捕获的两种控制策略；最后给出了一个空间圆编队捕获实例，并从燃料消耗、施加冲量次数及捕获时间等角度对比研究了两种控制策略的特点。

Because of the nonuniqueness in the positional solution, it's not easy to test the performance of the coordinated control system. So the model of NN was built to convert the vector of the length of 6 jars into the vector of the position of the motion deck. It's fast and accurate for the lengthwise direction. The state space system model of the six degree freedom motion simulator was built by the equations of electrodraulic servo mechanism and the multi-body dynamics equation of the six degree freedom motion simulator,the vector of the length of 6 jars was the control variable.

Four chapters in the first volume, including "The Origin of Movement","Thinking of Effort","Movement Space" and "To Find Body", develop the theoretical structures of body language in western modern dance, analyze elements of movements and their semantic characters, reveal the conceptual transformation in the science of modern human movements and science of body language, and discover the re-interpretation through modern dance about the essence of movement and space and time of movement Another four chapters in the second volume including "Feminized Body""Masculine Body""Sex-confused Body" and "Body's Origin", study respectively features of body language in the field of ballet, modern dance and post-modern dance, provide a chronicle embodying the form variation of body language through lineal comparison, and exposit spiritual pursuit and value preference of modern choreographers and their relationship with history and culture. Therefore, effective body strategy of "Back to Body's Origin" in today's human existence is offered and teaches us how to keep our own national culture in the times of cultural globalization and integration.
